[SOLVED] Rails on PSU

[fede.3d]

Hi all, i buyed a power supply from itek that has 4 rails on it. (12v1,12v2,12v3 and 12v4) I wanted to ask how they work? There are some differences from other PSUs? (anyway, this is the psu in question: http://www.itekevo.com/en/product/alimentatore-desert-plus-700/?ice-lang=en )

It says
MAX OUTPUT CURRENT (+12V1)18 A
MAX OUTPUT CURRENT (+12V2)18 A
MAX OUTPUT CURRENT (+12V3)18 A
MAX OUTPUT CURRENT (+12V4)18 A

depending on the PSU, it means 12v ATX 4pin connector, 24 pin mainboard connector, 4 pin molex connector, PCI-E connector etc..
